Geo-hazard Forecast Based on Grey Model in Mine Area

This paper studies landslide and background in Youyu County, Shanxi Province and provides geological bases for the economic and social development, ecological environment construction and protection. The authors investigated the environmental geological background, collected and arranged the information in this field. By analyzing Landslide-causing factors, the area is divided into four types: high susceptible area, middle susceptible are, low susceptible area, difficult susceptible area. A map of Landslide hazard susceptible degree is made, based on the studies of the quantitative indices (formation lithology, slope structure type, gradient, rainfall, slope height, engineering activities, slope deformation features, death and threatened toll, direct and indirect economic loss and so on.).And the Landslide hazard risk of the area is comprehensively assessed.

Assessing Risk Economically on Landslide in Youyu County, Shanxi Province

According to onsite investigation and analysis of the geo-hazards in Youyu County, their main types are identified as landslide,collapse,debris flow and surface collapse.The causes are analyzed in terms of topography,lithology,rainfall and other factors.The research result has shown that the geo-hazards of Youyu County is closely related to rainfall and human engineering activities.The paper suggests that standardized management of the engineering activities and flood season monitor are critical to the geo-hazards counter measures in Youyu County.

Analysis of Development Characteristics and Formation Mechanism of Geo-hazards in Youyu County,Shanxi Province

This paper studies the environmental geological problems about collapse and background in Pinglu district of Shuozhou City, Shanxi Province and provides geological bases for the economic and social sustainable development, ecological environment construction and protection of the district. The authors investigated the environmental geological background, collected and arranged the information in this field. By analyzing collapse-causing factors, the area is divided into four types: high susceptible area, middle susceptible are, low susceptible area, difficult susceptible area. A map of collapse hazard susceptible degree is made, based on the studies of the quantitative indices (formation lithology, new structure activities and earthquake, gradient, rainfall, slop height, engineer activities, happening scale and frequency of collapse, death and threatened toll et al.). And the collapse hazard risk of the area is comprehensively assessed.

Risk assessment on collapse in Pinglu district of Shuozhou City, Shanxi Province

This paper studies the environmental geological problems of Dashikou landslide. The author analyzed main land slidecausing factors and evaluated stability of landslide by use of Rosenbluth method. The assessment result is 0.98. The result indicated that the landslide was in extremely unstable stage. The author predicted hazardcausing economic losses and casualties to human beings. Finally some methods and suggestions in risk management were advanced in this paper. Keywords: landslide; hazard; risk; management; assessment

Risk Management Assessment in Landslide in Dashikou of Ying County, Shanxi Province

This paper studied a forecasting method of geological hazard in loess plateau mining area, by making use of a grey system theory and building grey model, it is expected that in 2018, the loss statistics of mining geology hazard in the area will increase steadily, the loss of water-inrush, slag, ground subsidence, landslide collapse and ground crack will reach relatively 623,480 dollars, 879,346 dollars, 75.833 km2/103km2, 811.295*104m3, 597,761 dollars in 2018. The prediction results provided geological bases for the economic and social sustainable development, ecological environment construction and protection.
